After the recent trial-and-error, one conclusion I have come to is that you guys were right. The Celestial Forge is even clunkier to work with if you
don't random-roll. The potential power in there is
immense, and the degree of randomness is necessary to slow your roll enough to actually have a story instead of a curbstomp. I tried alternate methods of slowing the pace in this story, and while they were working they weren't working
great.
Pure random-roll of course has its own drawbacks, as "Light of the Forge" proved, but in hindsight I did hit on something valid there with 'random roll but veto and/or pick something less awesome than your roll'. It lets you slow the roll, but you don't have to give any artificial excuses for not speeding the roll up. If the dice don't give it to you, you don't get it, even if you can maybe get a lesser consolation prize.
Of course, I've already
tried a "Light of the Forge". So I don't think I'll ever actually try the Celestial Forge again. Two experiments, two different approaches at using it, two failures at roughly the same point. Abandoning a fic depresses me somewhat, so, when I finally try again - at whatever indefinite future date - I shall very likely try something else.
Inspired Inventor, OTOH, has the problem of too much too fast. This works in Worm v1 CYOA because Worm's a fucking cosmic death world, you literally cannot be too powerful there for the plot. Even Kaleidoscope with the chain taken COMPLETELY off at least still lets you get out a complete one-shot (as
I've already demonstrated, plug plug) off. The solution taken by
Slayer Anderson's
"Industrious", which has II exist but
really slows down the recharge rate (in that fic, its 1 charge/month) looks very promising, and I already recced that fic earlier but by all means I'll rec it again. So, that's a long-range possibility. Although right now there's a fic doing it and doing it really well, so I ain't gonna head-to-head against that.
One other suggestion was Tinker of Imagination. That one I probably won't ever use - the ability to ignore the Tinker Cycle and conjure your own materials and specialized tools from the getgo means that any MC I wrote couldn't NOT go all SupCom inside the first 24 hours. As for regular Tinker of Fiction... I've read ToF fics, and the fun there is using all sorts of obscure stuff from obscure franchises in creative ways, and I do not know as many franchises as those guys do.
I do have an
Essence of the Innovator I might use in a future tech-wank fic, and which I'll link here so people actually remember it exists. It's old and obscure.
tldr; We'll see what the future brings someday, but it likely won't be the Celestial Forge again.
